So the SATA controller is already in AHCI mode. Good. You didn't say what kind of server hardware you are using or I missed it. On the HP DL3xxx servers we usually use, we have to enable AHCI mode _and_ the write cache in the BIOS. Maybe your server needs something similar. Some RAID controllers only allow you to enable the write cache when a battery-backed write cache module is installed.
